Better Url Handling for web.py

In my post about web.py I touched upon the fact that I don’t like web.py’s way of defining URL’s, that I find it too loose. Well, it’s a minor problem, but rather trivial to solve, so I did. As quoted in the original post, there is a bit more typing, but I personally prefer this solution. (To be fair, the example I gave in the original post can be applied to this code as well, but I’d say this makes it a tiny bit more readable):

def webpyurl(_tuple):
    """
    Map a structured tuple to a url that web.py will accept.

    Turns a tuple of the format
    (
        ('a', 'b'),
        ('c', 'd')
    )
    into
    (
        'a', 'b',
        'c', 'd'
    )

    Rather simple, but can make a huge difference in readability.

    @require enhancedappend()
    """

    thislist = []

    for (a,b) in _tuple:
        enhancedappend(thislist, a, b)

    return tuple(thislist)

def enhancedappend(_list, *appends):
    """
    list.append only takes 1 argument, this allows for more to be added
    """

    for append in appends:
        _list.append(append)

This code is also available on pyhacker.
